Independently of one another, the Doctor and Donna Noble are investigating Adipose Industries who claim to have created a revolutionary diet pill. The head of Adipose, Miss Foster, runs a pretty tight ship and they have been quite successful. Donna visits several people who have taken the pills and as advertised, the pills seem to be working. Except of course for the person that virtually vanishes, excerpt for a strange little creature in the bathroom sink. The Doctor and Donna join up eventually and come to the realization that there is definitely something alien behind what is going on. Written by garykmcd

Donna Noble: [Donna aproaches a stranger] Listen, there's a woman going to come along. Tall blonde woman called Sylvia. Tell her, that bin there. It'll all make sense.
[She heads back to the TARDIS, toward the past, future and everything in between. The stranger she was talking to turns back towards the camera - she is ROSE TYLER. Looking worn, depressed. She turns back around, walks away, and then simply vanishes into thin air... ]

A big ball of fun with stunning characterisations
19 August 2015 | by Sleepin_DragonSee all my reviews

Series 4 kicks off in rather quirky style, a fat fighting conglomerate are using a telephone sales company to push its pills. They seemingly have flawless results until the fat turns into cute little figures. Head of the corporation is a very spiky humourless Miss Foster, played by the tremendous Sarah Lancashire. The Doctor is battling loneliness and seems ready for a new companion.

I know it has a slight CBBC feel to it with regards the Adispose, they are so damn cute, i'd still love to have one.

As likable as Martin Ball is playing Roger Davey, could they not have got a chunkier actor, he's tiny :-)

Love Donna's insults towards Martha, who fancied the Doctor, mad Martha, charity Martha...... Martha suffered from the Rose hangover, that would not be Donna's fate. I love how she bamboozles him.

OK so it's not the best story, and there are some elements that belong to the Mr Tumble show, but the characterisations are superb, Sarah Lancashire is great, Sylvia Noble is fun and Bernard Cribbins is an absolute joy, but I will forever love Partners in Crime for giving us Donna, to this day my all time favourite companion, I long for her return still!! She proved so many people wrong, she had the lot.

That little glimpse of Rose made my heart sink, it changed the mood, what a clever shift in gears, and how pretty does she look!!!!

Flawed but tremendous fun 8/10
